Question about Django Rest Auth and Users

I am using Django Rest Auth endpoints and DRF for learning. I created a basic To-Do app and it works just fine but after I have new users register, I would like them to be able to do basic CRUD operations on their own tasks.

Because I am using Django Rest Auth to register users, is there anything special I need to override? How would I go about achieving this goal?

I feel like this may be an easy problem to solve but I'm having trouble. I've tried adding to views.py

permission_classes = (IsAuthenticated,)

but does not work.

Thanks for any help!

SQLAlchemy filter similar entries

I'm asking myself how to implement a proper search function. For example in the case of a User database model created with sqlalchemy. How would I do a filter request searching for similar names as the given one?
E.g.:


User.query.filter_by(name="Tina").all()
# gets all users with the name "Tina"


But what if I want to get all users with a similar name as well? E.g. "Tine", "Lina"
Is there something more efficient than looping through the name letters replacing it with % and do like or ilike queries?

Spyder causing tons of terminal/console windows to rapidly open and close. WHy and how do I fix it?

The title pretty much says it all. This happens with a whole range of things I try to do, and actually it seems like everything I do causes this.

The only other information I can provide, is that the file address in the "Title" bar of the terminal window ends in "tput.exe", but it's opening and closing so rapidly (and so many times) that I have a hard time making out anything else. Anyone know whats up?

To clarify, I just ran `x = []` and had to wait 10 seconds for a ton of terminal windows to open and close. It's SUPER annoying.

Trouble getting Filtering working with ViewSet

I'm relatively new to Django but generally have figured out how to use filtering quite effectively. However, I have encountered a situation that I can't resolve:

class FeatureStatsViewSet(ModelViewSet):
queryset = FeatureStats.objects.all()
serializer_class = FeatureStatsSerializer
permission_classes = (permissions.IsAuthenticated,)

# TODO: Not sure why this is only returning one record during testing!
def get_queryset(self):
user = self.request.user
pipelines = Pipeline.objects.filter(createdBy=user.id)
features = Feature.objects.filter(pipeline=pipelines)
return FeatureStats.objects.filter(feature=features)
#return FeatureStats.objects.all()


What this code is supposed to do is return 'FeatureStats' for the currently authenticated user. My approach has worked correctly for lots of other tables but not for this one.

"FeatureStats.objects.all()" returns all 10 records in my test data, which is correct.
"FeatureStats.objects.filter(feature=features)" is supposed to return 9 records, which are the ones that belong to the currently authenticated user via the Pipeline class, which has a UserId field. Unfortunately it only returns 1 record.

I added "print()" statements from top to bottom in the aforementioned code. Everything appeared correct down to "features", which showed only the 11 features connected to the authenticated user and not the 1 feature which belonged to another user. But then the last statement just doesn't function correctly, returning only one record.

Any ideas what I might be doing wrong?

Can anyone suggest a website where I can hire someone to teach me how to program in python?

I understand there are many places to learn it for free online. I don't have time to fumble around with it.

I would like to learn it quickly and with less frustration.

Does anyone know where I can find a one on one teacher?

[D] Did I get too far ahead of myself?

For the past 1.5 years I've been interning as an undergrad research engineer on ML, and I am getting results, and some of it is going to be published. From this perspective, it looks like I am doing quite ok, but in reality I have no idea what I am doing, and the paper(s) that I'll be publishing won't even be close to the quality of the papers that I'm reading. My understanding of ML algorithms is at a black box level, but I have a decent understanding of what approach I should take for a problem, and domain knowledge in the field that I'm applying ML to. However, my math understanding is terrible, and I can't even count to potato. I ignore the math problems and move on to problems that I am able to solve, but this severely limits my usefulness and I'm unable to reproduce most of the new research papers.

I came from a biology background, but I've been programming and reading up about comp sci topics ever since I was a kid. Never good at math, and that's the reason why I wasn't eligible for a math/compsci major, and had to self-study my way into this field.

At this point I am uncertain whether I am just overwhelmed by this new field, and that I should just continue applying ML and hopefully learn and understand it this way, or that I will eventually hit a wall and get stuck as a half-assed biologist and half-assed computer scientist. Instead of continuing with getting practical experience, I could take a few steps back and formally enroll for math/comp sci courses for a couple of years and take the usual safe route. In the long term, I would like to end up a tech company as a research engineer, but I feel like if I don't get a degree in math/comp sci, I will never be confident in my math skills and have a hard time getting past technical interviews.

Thanks for taking the time to read this. What do you guys think?

Question on Libraries for Terrain

Hey there fellow Python aficionados!

I'm starting on a project that maps terrain data in Alaska and I honestly have no idea where to begin or what libraries to use. Hell, I can't even figure out where to get the data!

Anyone have any guidance? I want to take and build contour maps at integer hundreds of feet levels throughout southwest Alaska. Ideally it'd be nice to also draw great circles to arbitrary points then measure four or five miles either side of course and find the highest elevation.

Google says matplotlib and basemap but the setup for basemap looks like a bastard. I'm open to learning another programming language if that would be the easiest way to do this, but I'm partial to Python and I'm most comfortable with it. Thanks for the help, this project is a little beyond the scope what I normally do.
